Reaction cross sections for 12C+12C
- 1. University of Notre Dame, Notre Dame, Indiana 46556
Description
The yields of the eleven most abundant nuclides produced in the 12C+12C reaction were determined in the energy range from 14 --31 MeV (c.m.) via γ-ray techniques. Several reaction channels, including a few which involve only light-particle emission, show strong structure. Some of these anomalies are very narrow, having widths < or approx. = 250 keV (c.m.). The 3α evaporation cross section, as well as the yield of 12C via direct inelastic scattering, is determined. Further information is presented on the nature of a process leading to anomalously large α-particle yields from the 12C+12C reaction at low energies. The strong gross-structure features of the fusion and total reaction cross sections are discussed in the context of the optical model, and also with reference to the limiting angular momentum for fusion. The latter analysis leads to some insight into the origin of the gross structure, but also suggests a striking correlation between the fusion cross section and the extended ground state band of 24Mg at high energies. This correlation, if it is not coincidental, has interesting consequences with regard to the behavior of 24Mg at high angular momentum and energy
